Setup: Host: Win10 for Serial Terminal, Ubuntu 16.04 VM for building android etc.
Device: iMX8M mini (on devboard from variscite)
The device is running, with the provided android, my app and test apps are running great, only they cannot find/discover bluetooth devices. Thus, I wanted to check configuration and function of the bluetooth module.
Problem: Commands dmesg, hciconfig, bluetoothctl, etc are not working:
1|imx8mm-var-dart:/ $ hciconfig
/system/bin/sh: hciconfig: inaccessible or not found
127|imx8mm-var-dart:/ $ su 0 hciconfig
su: failed to exec hciconfig: No such file or directory
What I did: Connect my development board to the PC via USB Cable. I am then able to connect via Serial Terminal PuTTY: Win10 command line terminal: putty.exe -v -sercfg 115200,8,1,n,N -serial com8
Then I get status information, startup information and I can enter commands, like "ls", resulting in line: "imx8mm-var-dart:/ $ ls" in the terminal.
What I noticed: Throughout my search I found examples of people using terminal commands like:
root@imx8mmevk:~# dmesg | grep "Bluetooth"
All my urgent questions:
I hope my question is precise enough and on-topic, please don't hesitate to comment on that, too.
